Can't get into recovery from bootloader - Nexus 7 General

Hi all. So I got myself into a boot loop and that usually isn't a big deal on a nexus. Power off. Boot into bootloader, and select recovery. Boom. well I am unable to get into recovery that way. I can reboot into recovery from a rom no problem. And I can adb into it with reboot recovery. Just not through the bootloader like usual.
Any thoughts?

Can't use an app if in boot loop.
You will need a computer and type
Adb reboot recovery
Or if you want bootloader
Adb reboot bootloader

Interesting. Haven't heard that. But would make sense. Twrp and cwm both wouldn't.
And yeah, fastboot commands work fine. So I wasn't lost. Just might not always be near my comp

If you get caught in a boot loop, here is how you need to get into recovery with the Nexus 7.
Hold volume up, volume down and power until it boots into bootloader.
Plug into USB on your Windows Computer.
Open Command prompt (in fastboot folder)
type: fastboot reboot-bootloader
It will now reboot into bootloader. You can now unplug the USB, scroll down to Reboot recovery, press power button, and it will reboot to recovery.
(Please note you have to be unlocked, rooted with a custom recovery to do this!!!)

Update, you don't have to use fastboot, or even have drivers installed. You just have to be plugged in to any comp usb. Mac windows whatever. Then you can enter recovery from bootloader. Wierd huh

Has this bug been fixed? Or will ever be? Need a cwm update or is it a Google problem?

Bootloader problem apparently. All recoveries, including stock can't access. Hopefully someone or Google will fix eventually

Doesn't work for me, when I do that, instead of hanging at the Google logo indefinitaly, it eventually reboots (crashes?) and boots up normally into Android.
But I'll try the "fastboot reboot-bootloader" while being in bootloader thing, if that works, good enough for me.
Yet yes, I hope they'll bring out a fixed bootloader - but I don't really think they will.

So there is still nothing we can do with that? ;c

Well custom rom's advanced power menu works, trinity kernel toolbox, goo manager I think, and apps like that all work. But if you bork it into a bootloop you'll need a USB connection.
Until there's an update from google or someone writes a new bootloader that's how it will be.

If it helps...
After much testing (and after update)
IT HAS TO HAVE USB when VOL DN +VOL UP + ON (only) from off
Later insertions do not work.
I bet it is not a bug, I bet they wrote code for external power check during entry to recovery, etc. Thus, I also bet it is deliberate, NOT a bug, and will not go away.
There are instructions all over the web about when to plug in, on mine it has to (only) be at VD, VU, +ON.
I made a list of operations and screen responses as I tested, if of value...

Iam using trinity tool to boot into recover. It is working fine.

I just had this problem. 2 hours ago I never had this issue.
This started happening when I flash Franco's kernel.
Before I can boot to recovery by going to bootloader then choose recovery. Now I can't!
I even flash stock / re-locked and it still a no go.
I can only boot from recovery thru fastboot or while inside Android.
WTH!
EDIT: Could it be related to the build?
Here are my findings:
a) I used my mom-in-law's nexus 7 stock, never rooted = c8O = It DOES not boot to recovery from hardware buttons (bootloader then choose recovery) - but It boots to recovery from bootloader only when it is connected via USB
b) I have a C9O which was working before, but I flashed to STOCK (recovery using the Toolkit) then It can't boot anymore - so it might not be Franco's kernel
c) Friend's C9O stock, never rooted = CAN boot to recovery without having to plug in the USB.
Weird .. so maybe google will fix this.

Had this problem last night after flashing the latest AOKP. Kept getting stuck at the google screen and couldnt get into recovery at all. I downloaded the Nexus toolkit and was back working in 2 minutes. Highly recommend to anyone who has a similar problem

Do you have ADB and fastboot software installed in your PC? Either have that or download Android SDK. You can boot your phone via ADB command lines.

Can you reach the boot menu by pressing the volume down key while powering on?
Otherwise, try to check if fastboot is able to see your device and flash some new boot and system image
You have a Nexus One, not sure why you're using the Nexus 7 Toolkit..

Thank you for asking. able to enter boot menu and fastboot menu. but cant flash anything, i'll tried new boot new system img's. Nothing. When connecting to PC fastboot showing Fastboot USB mode is enabled. unable to do nothing via adb mode. adb mode say error device not found.
Thanks for answer
Are drivers installed? And have you installed adb and fastboot correctly?

Yes, installed correct. it show up in the Device Manager list.
Anyway, i go to try this driver. Thanks. Let me know u
hmm. unlucky. Still nothing. Windows take a signal when connecting phone shows on fastboot menu => fastboot usb and adb mode say error device not found:crying:
i scanned my drivers using driver genius v11, i saw android driver named Samsung_Android_4.0_usbdrivers. now i think its something wrong with my boot.img?
When you see fastboot usb, and you type fastboot devices in a terminal, what does it say? ADB only works in recovery or when your ROM is booted, so just focus on fastboot.
it say when N1 is fastboot usb mode "error device not found". thanks for advance. tomorrow i'll be ask more.

Hey guys. Finally my N1 detected in adb mode. Im used Nexus 7 toolkit, downloaded N1 official Rom (i used only boot.img from zip file)

It's one of the "unlockable" models. Use the "unlock-relock" tool or the unlock script from the unlock guide.

If this helps,whenever I boot into recovery now,a red text saying LGE SECURITY ERROR: BOOT IMAGE or something like that
So you flashed a recovery before unlocking?
If your device doesn't boot at all, do a kdz reflash. If you can boot to the system, use one of the methods mentioned above; you only need root and USB debugging on to use it. If you don't have root but can't boot to recovery, try the "root many android" method from the index, that might do it. If it still fails, do a kdz reflash, then start again (root - unlock - recovery)

I have a unlocked X, was trying to install a new rom via recovery and something went wrong...but I forgot to do backup so now its on a boot loop and I didnt have USB debugging enabled. Is there anyway to load new another rom to the phone so that I can install via recovery since I dont have usb enabled?
Yes power the device off by holding the power button and volume down, after the display is off let go of the power button. You can flash recovery or boot to recovery from there

I can boot into recovery but how do I transfer the new rom to the phone so I can install via recovery? I dont know how to move it from my PC to the phone.
You should look up side loading via adb and most newer recoveries allow you drag and drop once it's booted, you are using a custom recovery for your phone correct?

First link, option 5. Had a similar problem where I can go to recovery but my internal was deleted...I had nothing. Nor did I have a system.....I couldn't restore a backup nor flash a new ROM. I had nothing but recovery....so I googled the 5.1 firmware update and modem....and followed option 5 with mfastboot. Phone is up and running fine.

Locked on Google Boot Screen.. Need Help

I need some big help. I was having issue with my battery and phone powering off when not on a charger. I thought change the OS with Android N beta could help me with the issue.. When I was complete the fastboot commands .. I mistakenly use the lock bootloader command as well. So my devices is suck on the Google Logo.. Can someone help me with this issue?

Well, try first doing a factory reset from the recovery mode.
If it doesn't help, just unlock it and flash everything again.
My bad.. I meant to add that its not let me unlock the bootloader.. Its asking me to select OEM unlock in the setting of my devices

Try doing the factory reset through recovery, and if it doesn't work, take this steps and sideload the ota:

Google makes OTA update zips available that can be flashed even if OEM Unlock is disabled. Assuming you are still able to access the bootloader, download the latest Nexus 6 Android 6.0.1 OTA and copy it to internal storage. Enter recovery and flash. This will wipe your entire system, but your phone will be operational again.
From there, you need to go through the process of unlocking the bootloader, and then you can try installing the N preview again.
